報(bào)告發(fā)現(xiàn)，溫室氣體達(dá)到創(chuàng)紀(jì)錄水平

The dominant greenhouse gases released into the Earth's atmosphere reached record levels in 2018, and their global warming power is now 43% stronger than in 1990, according to a new report by the American Meteorological Society released Monday.

美國氣象學(xué)會(huì)(American Meteorological Society)周一發(fā)布的一份新報(bào)告顯示，2018年，排放到地球大氣中的主要溫室氣體達(dá)到創(chuàng)紀(jì)錄水平，它們的全球變暖力量比1990年強(qiáng)43%。

The State of the Climate in 2018 study also reported other key findings:

2018年的氣候狀況研究還報(bào)告了其他重要發(fā)現(xiàn):

· 2018 was the fourth-warmest year on record. The three other warmest years were 2015, 2016 and 2017, with 2016 as the warmest year since records first began being kept in the mid-1800s.

2018年是有記錄以來氣溫第四高的一年。另外三個(gè)最熱的年份是2015年、2016年和2017年，其中2016年是自19世紀(jì)中期有記錄以來最熱的一年。

· Sea levels rose to record levels for a seventh consecutive year.

海平面連續(xù)第七年升至歷史最高水平。

· Glaciers continue to melt at a concerning rate for the 30th straight year.

冰川繼續(xù)以令人擔(dān)憂的速度融化，這已經(jīng)是連續(xù)30年了。

"Every year since the start of the 21st Century has been warmer than the 1981-2010 average," the report said. "In 2018, the dominant greenhouse gases released into Earth's atmosphere -- carbon dioxide, methane, and nitrous oxide -- continued to increase and reach new record highs."

報(bào)告稱:“自21世紀(jì)初以來，每年的氣溫都高于1981年至2010年的平均水平。”“2018年，排放到地球大氣中的主要溫室氣體——二氧化碳、甲烷和一氧化二氮——繼續(xù)增加，并達(dá)到新的歷史高點(diǎn)。”

In fact, the report found greenhouse gases warming influence on the planet have increased an alarming 43% since 1990. Global carbon dioxide concentrations, which represent the bulk of the gases warming power, rose during 2018 to a record 407.4 parts per million, the study found. That is "the highest in the modern instrumental record and in ice core records dating back 800,000 years," the report said.

事實(shí)上，該報(bào)告發(fā)現(xiàn)，自1990年以來，溫室氣體對(duì)地球變暖的影響已經(jīng)驚人地增長了43%。研究發(fā)現(xiàn)，全球二氧化碳濃度在2018年升至創(chuàng)紀(jì)錄的407.4 ppm。二氧化碳濃度占全球變暖動(dòng)力的大部分。報(bào)告稱，這是“80萬年前現(xiàn)代儀器記錄和冰核記錄中最高的”。

The report was led by National Oceanic and Atmospheric Administration's Centers for Environmental Information and was based on contributions from more than 475 scientists from 57 countries.

該報(bào)告由美國國家海洋和大氣管理局的環(huán)境信息中心牽頭，基于來自57個(gè)國家的475多名科學(xué)家的貢獻(xiàn)。

Scientists used tens of thousands of measurements from multiple independent datasets to reach their findings.

科學(xué)家們使用了來自多個(gè)獨(dú)立數(shù)據(jù)集的數(shù)萬次測量數(shù)據(jù)來得出他們的發(fā)現(xiàn)。

"This is yet another in a series of expert, science-based reports that continue to sound the alarm about the climate crisis," said Marshall Shepherd, a professor of Geography and Atmospheric Sciences at the University of Georgia. He is also a former president of the American Meteorological Society.

佐治亞大學(xué)地理和大氣科學(xué)教授馬歇爾·謝潑德(Marshall Shepherd)說:“這是一系列以科學(xué)為基礎(chǔ)的專家報(bào)告中的又一份，這些報(bào)告繼續(xù)敲響氣候危機(jī)的警鐘。”他也是美國氣象學(xué)會(huì)的前任主席。

Shepherd went on to say that the "climate change is clearly seen now in our weather, agriculture productivity, water supply challenges, public health, and even national security concerns."

謝潑德接著說，“在我們的天氣、農(nóng)業(yè)生產(chǎn)力、供水挑戰(zhàn)、公共衛(wèi)生上，甚至國家安全問題上上氣候變化清晰可見。”

"The findings from their State of the Climate report rises above some blog or opinion on social media," Shepherd said. "Through the process of science, they are sounding an alarm about the 'here-and-now' climate crises."

謝潑德說:“他們對(duì)氣候狀況報(bào)告的發(fā)現(xiàn)超越了一些博客或社交媒體上的觀點(diǎn)。”“通過科學(xué)的進(jìn)程，他們?yōu)?lsquo;此時(shí)此刻’氣候危機(jī)敲響了警鐘。”

Sea levels continue to rise

海平面持續(xù)上升

Monday's report found that global annual sea levels rose for the seventh consecutive year and hit a record high for the 26 years since satellite.

周一的報(bào)告發(fā)現(xiàn)，全球海平面連續(xù)第七年上升，并創(chuàng)下衛(wèi)星發(fā)射以來26年來的新高

"The new high reflects an ongoing trend," the report said. "Ongoing trends and year-to-year changes in sea level impact coastal communities by increasing the magnitude and frequency of positive sea level extremes that cause flooding and erosion."

報(bào)告稱:“這一新高反映出一種持續(xù)的趨勢。”“持續(xù)的趨勢和海平面年復(fù)一年的變化，通過增加海平面極端現(xiàn)象的程度和頻率(這種極端現(xiàn)象可導(dǎo)致洪水和侵蝕)，對(duì)沿海社區(qū)產(chǎn)生影響。”
